Which Kamen Rider series are you currently watching at the moment? Aside from Fourze, I'm currently going through Kiva and Ryuki and enjoying both. Only on episode 5 of Kiva and episode 11 for Ryuki. Ryuki is a bit dated and feels light on fighting, but has a good story. Kiva's ok but Wataru's not that likable as a character.

Been trying to work my way through it for the better part of a year really. lol. I'm around episode 20 now. I jsut haven't had much interest in it thus far. Between that Fourze and Gokaiger I'd also like to get back through Blade and Kabuto

Pros:
Aesthetics/Designs: I LOVE the Fangire designs and the whole stained glass motif. The Rider suits/designs are also great, my love for Rising Ixa has grown now that I know he basically casts off ala Kabuto.
Otoya: I don't really need to explain this one, Otoya's just a great character.
Dual Storylines: I felt this helped the pacing of the overall episodes a lot, since Kamen Rider is so bent on always being 2-part episodes this makes it so you don't need to overstretch the plot because you have 2 to work with.
Arms Monsters: Rikki(Bassha) and Ramon(Dogga) were criminally underused but I really liked these 3. Jirou's actor was also great, I look forward to seeing him in Hibiki.
Kivat: Just a fun little bat-thing.

Cons:
Character Regression/Assassination: This series took characters I liked (or hated then liked in Nago's case) and then destroyed most of them. Kengo became an asshole, Nago became comedy relief right after I grew to like him, Wataru's regression to being a total shut in really hit me the wrong way, and Mio, ugh. I see what Inoue was trying to do with Mio and Kengo, but they were done better in Kabuto as Hiyori and Yagaruma/KickHopper.
Love Triangles/Love driven plots: I'm just not a fan of love triangles and using love to drive the plot forward. YMMV on this one, but I didn't like how a good chunk of the show relied on this, both 2008 and 1986 timelines.
Miscommunication: Probably my most hated Inoue trope. So much could be solved in 2 minutes if you just sat down and actually said what you think/feel!

Not sure if I'd recommend this series or not, but there are definitely better Rider shows to start with
